Suppose that-- ignoring, for the moment, of the bad optics and questionable political science behind such a decision-- that Joe Biden were to choose a white male for his running mate.
A bit unrelated, but why would it be bad optics and questionable political science? Biden should pick the most qualified running mate regardless of race and gender
A fair enough concern to raise. I'd say 1) He's already pledged to pick a woman; and 2) Given how diverse the Democratic Party is, picking two people from the most privileged sex and race is problematic. Especially now that we have dozens and dozens of qualified women and persons of color.
